Tannic acid (Gallotannic acid), a polyphenolic compound, is a CXCL12/CXCR4 inhibitor with antiangiogenic, anti-inflammatory and antitumor activity.
Tannic acid, at nontoxic concentrations, specifically inhibits CXCL12-induced human monocyte migration (IC50, 7.5 μg/ml) but does not inhibit CCL2-, CCL3-, CCL5-, formylmethionylleucylphenylalanine (fMLP)-, or C5a-induced migration. The compound markedly blocks CXCL12 binding to THP-1 cells (IC50, 0.36 μg/ml). Tannic acid also inhibits CXCL12-induced, but not epidermal growth factor-induced, migration of MDA 231 breast tumor cells. Additionally, 0.5 μg/ml of tannic acid selectively inhibits CXCL12-mediated, but not basic fibroblast growth factor- or endothelial cell growth supplement-mediated, bovine aorta endothelial cell capillary tube formation[1].
Given in drinking water, tannic acid enhances the survival rate of mice bearing syngeneic tumors[1].

Tannic acid: a versatile polyphenol for design of biomedical hydrogels
Tannic acid (TA), a natural polyphenol, is a hydrolysable amphiphilic tannin derivative of gallic acid with several galloyl groups in its structure. Tannic acid interacts with various organic, inorganic, hydrophilic, and hydrophobic materials such as proteins and polysaccharides via hydrogen bonding, electrostatic, coordinative bonding, and hydrophobic interactions. Tannic acid has been studied for various biomedical applications as a natural crosslinker with anti-inflammatory, antibacterial, and anticancer activities. In this review, we focus on TA-based hydrogels for biomaterials engineering to help biomaterials scientists and engineers better realize TA's potential in the design and fabrication of novel hydrogel biomaterials. The interactions of TA with various natural or synthetic compounds are deliberated, discussing parameters that affect TA-material interactions thus providing a fundamental set of criteria for utilizing TA in hydrogels for tissue healing and regeneration. The review also discusses the merits and demerits of using TA in developing hydrogels either through direct incorporation in the hydrogel formulation or indirectly via immersing the final product in a TA solution. In general, TA is a natural bioactive molecule with diverse potential for engineering biomedical hydrogels.
Tannic acid-based functional coating: surface engineering of membranes for oil-in-water emulsion separation
Tannic acid-based functional coatings, as a green, universal and versatile tool to manipulate surface properties, have received extensive attention in the field of surface engineering of membranes for oil-in-water emulsion separation. With the rapid development of this field, more flexible and efficient modification strategies for surface engineering of membranes have been developed recently. It is therefore critical to update the broader scientific community on the important advances in this field. Here, we summarize recent progress in surface engineering of membranes with tannic acid-based coatings for oil-in-water emulsion separation. The chemical properties of tannic acid and how to design TA-based functioanl coatings via physical/chemical regulation are discussed. The roles of tannic acid in surface engineering of membranes are highlighted and classified into the following five categories: changing surface wettability, adjusting surface charge, constructing catalytic surfaces, forming hydrogel surfaces, and fabricating hybrid separation membranes/layers. Finally, the future outlook and the challenges in this field are discussed.
Tannic acid-based metal phenolic networks for bio-applications: a review
Tannic acid (TA), a large polyphenolic molecule, has long been known for use in food additives, antioxidants, bio-sorbents, animal feed and adhesives due to its intrinsic properties such as antioxidation, metal chelation, and polymerization. Recently, there has been a renewed interest in fabricating engineered advanced materials with TA modification for novel bio-applications. The modification process involves various interactions/reactions based on its diverse chemical structure, contributed by abundant aromatic rings and hydroxyl groups. In addition, the obtained composites are endowed with retained TA activity and novel enhanced properties. Therefore, the aim of this review is to highlight the recent biomedical application of TA-based metal phenolic networks (TA-MPNs) by focusing on their intrinsic properties and the endowed ability for novel engineered functional composites. The potential contributions of TA-MPNs in "Tumor Theranostics", "Anti-Bacterial Ability", "Wound Repair for Skin Regeneration" and "Bone Tissue Regeneration Applications" are summarized in this paper.
Recent Advances in Tannic Acid (Gallotannin) Anticancer Activities and Drug Delivery Systems for Efficacy Improvement; A Comprehensive Review
Tannic acid is a chief gallo-tannin belonging to the hydrolysable tannins extracted from gall nuts and other plant sources. A myriad of pharmaceutical and biological applications in the medical field has been well recognized to tannic acid. Among these effects, potential anticancer activities against several solid malignancies such as liver, breast, lung, pancreatic, colorectal and ovarian cancers have been reported. Tannic acid was found to play a maestro-role in tuning several oncological signaling pathways including JAK/STAT, RAS/RAF/mTOR, TGF-β1/TGF-β1R axis, VEGF/VEGFR and CXCL12/CXCR4 axes. The combinational beneficial effects of tannic acid with other conventional chemotherapeutic drugs have been clearly demonstrated in literature such as a synergistic anticancer effect and enhancement of the chemo-sensitivity in several resistant cases. Yet, clinical applications of tannic acid have been limited owing to its poor lipid solubility, low bioavailability, off-taste, and short half-life. To overcome such obstacles, novel drug delivery systems have been employed to deliver tannic acid with the aim of improving its applications and/or efficacy against cancer cells. Among these drug delivery systems are several types of organic and metallic nanoparticles. In this review, the authors focus on the molecular mechanisms of tannic acid in tuning several neoplastic diseases as well as novel drug delivery systems that can be used for its clinical applications with an attempt to provide a systemic reference to promote the development of tannic acid as a cheap drug and/or drug delivery system in cancer management.
Pharmacological effects and mechanisms of tannic acid
In recent years, increasing attention has been paid to the pharmacological efficacy of tannins. Tannic acid (TA), the simplest hydrolysable tannin that has been approved by the FDA as a safe food additive, is one of the most important components of these traditional medicines. Studies have shown that TA displays a wide range of pharmacological activities, such as anti-inflammatory, neuroprotective, antitumor, cardioprotective, and anti-pathogenic effects. Here, we summarize the known pharmacological effects and associated mechanisms of TA. We focus on the effect and mechanism of TA in various animal models of inflammatory disease and organ, brain, and cardiovascular injury. Moreover, we discuss the possible molecular targets and signaling pathways of TA, in addition to the pharmacological effects of TA-based nanoparticles and TA in combination with chemotherapeutic drugs.
